Merge tag 'drm-intel-next-2014-06-20' of git://anongit.freedesktop.org/drm-intel into drm-next
- Accurate frontbuffer tracking and frontbuffer rendering invalidate, flush and
flip events. This is prep work for proper PSR support and should also be
useful for DRRS&fbc.
- Runtime suspend hardware on system suspend to support the new SOix sleep
states, from Jesse.
- PSR updates for broadwell (Rodrigo)
- Universal plane support for cursors (Matt Roper), including core drm patches.
- Prefault gtt mappings (Chris)
- baytrail write-enable pte bit support (Akash Goel)
- mmio based flips (Sourab Gupta) instead of blitter ring flips
- interrupt handling race fixes (Oscar Mateo)
And old, not yet merged features from the previous round:
- rps/turbo support for chv (Deepak)
- some other straggling chv patches (Ville)
- proper universal plane conversion for the primary plane (Matt Roper)
- ppgtt on vlv from Jesse
- pile of cleanups, little fixes for insane corner cases and improved debug
support all over
